Description |
|---|---|

<ESC>R<ESC>r<ESC>R |
Reset. If the server is a BIOS with control of the serial port and reset is supported, the system MUST be reset within 5 seconds. If the server is a UPS, an application-specific integrated circuit (ASIC), a service processor, or a software driver, and has control of the serial port, the server MUST be reset within 1 second. |
|
<ESC>( |
Invoke the server ASIC or service processor. After detecting this command sequence, the server ASIC or service processor MUST take control of the server serial port for console input/output (I/O). The server ASIC or service processor MUST return an Acknowledge Sequence within 1 second. |
|
<ESC>) |
Invoke the UPS processor. After detecting this command sequence, the server UPS processor MUST take control of the server serial port for console I/O. The server UPS processor MUST return an Acknowledge Sequence within 1 second. |
|
<ESC>* |
Acknowledge sequence. This response MUST be returned by the server UPS, ASIC, or service processor before any other server response, and within 1 second after it is invoked. |
|
<ESC>Q |
Exit without displaying the user interface. The server UPS, ASIC, or service processor MUST immediately release control of the server serial port, without interaction with the client. |
|
<ESC>^ |
Wake up. This requests that the server ASIC or service processor turn on the server within 1 second or wake the server from sleep state S1–S4 (for more information on sleep states, see [ACPI]). If the server is already turned on, server operation MUST NOT be disturbed. The server ASIC or service processor MUST return an Acknowledge Sequence within 1 second. |
